Polyester fibre: Feedstocks

Integration from refinery to yarn decides who wins

What this tab covers What it is made from and what it feeds: the raw materials and energy per tonne with their share of cost (linked to the commodity table), who is low-cost and why, and the chemicals made from it.

Polyester fibre is about 80% PTA and MEG by cost, so competitiveness rests on integration back to paraxylene and ethylene oxide, plus plant scale and power cost. Chinese groups run from refinery to yarn on one site. In India, Reliance is similarly integrated, while smaller spinners buy chip or inputs at import parity.

Who is low-cost, and why

Integrated Chinese groups sit at the bottom of the curve. Reliance is competitive in India. Non-integrated spinners in Southeast Asia, Turkey and India pay import-parity prices for PTA and MEG, which is why India's QCOs on those inputs raised costs for downstream weavers.
